Turn ratio of a step-up transformer is 1 : 25. If current in load coil is 2A, then the current in primary coil will be :

A

25A

B

50A

C

0.25A

D

0.5A

Text Solution

Verified by Experts

The correct Answer is:
B
Note : Load coil = Secondary coil
`E_(s)/E_(p)=N_(s)/N_(p)=I_(p)/I_(s) implies 25/1 = I_(p)/2`
Therefore `I_(p) = 50 A`
